Making an impression since its introduction at CES 2025, the Roborock Saros Z70 is the first robot vacuum cleaner to integrate the OmniGrip mechanical arm. This innovation enables the automatic pickup of items. In this Roborock Saros Z70 quick review, we highlight how its capacity to recognize and handle 108 everyday household objects significantly boosts cleaning efficiency—especially for homes with small children or pets.

This sweeping robot vacuum cleaner combines advanced functionality with stylish design, making it the top choice for vacuuming and mopping in modern homes.

Roborock Saros Z70 Quick Review: Best Vacuum Cleaner and Mop with Mechanical Arm

Slim robot with a streamlined, modern charging station

The first thing that impressed me the most about the Saros Z70 is its luxurious and modern design. You can choose from two main color options – black or white. Our Roborock Saros Z70 quick review version is black. A glossy, mirror-like coating covers the robot’s mechanical arm and the front of the charging station. It shifts color from black to silver depending on the viewing angle and lighting conditions. This not only enhances the aesthetics but also makes the product stand out from its competitors.

Not stopping there, the Roborock Saros Z70 continues to demonstrate sophistication in its overall design. The smart floor cleaner’s flat style and compact design highlight the unique identity of the Saros line. The engineers optimized the robot’s structure to just 7.98 cm thick. This allows it to easily slip into tight spaces under cabinets or beds—places traditional vacuums struggle to reach. They also integrated the LiDAR sensor cluster directly into the body, removing the bulky protrusion seen in the previous generation. This delivers a “super slim” design that still maintains precise positioning and navigation.

Despite its many positive design features, the Saros Z70 also has a few aspects that I find somewhat regrettable. Replacing the touchscreen used in older models like the Saros 10 (Hands-On) or 10R with mechanical keys is inconvenient. Redesigning the trash bag cover and floor cleaning solution tank at the charging station also adds complexity. These changes are less convenient compared to the push-to-open mechanism.

Roborock efficiently integrates the redesigned dustbin and water tank components, making maintenance easier without sacrificing performance. The Roborock Saros Z70 comes in a basic box with a user manual and a cardboard carrying case. This case involves setting up the robot to pick up items for use during cleaning.

First & Best Vacuum cleaner and Mop with Mechanical Arm

Undeniably, the OmniGrip mechanical arm sets the Saros Z70 apart—this breakthrough technology doesn’t exist in any other product within the robot vacuum cleaner segment. The first look when viewing the product is the feeling of “surprise” when the 5-axis arm automatically opens to pick up small items lying on the floor. You can imagine that, with this ability, the robot will not encounter obstacles stacked by items such as socks and shoes scattered on the floor.

The OmniGrip arm uses its advanced sensor system, camera, and LED lights to accurately locate objects, evaluate the surrounding environment, and determine the weight of each item before picking it up. According to the company, the intelligent sweeping robot can accurately identify up to 108 everyday household items weighing no more than 300g, including socks, shoes, and scarves. Users can also label up to 50 additional items. This helps expand the arm’s usefulness during cleaning. During use, the Saros Z70 works very effectively with moderately sized items such as pairs of shoes or small socks.

However, for items that are too small or do not have suitable hook points, such as baseball caps, the OmniGrip arm cannot really “conquer” them.

Another notable feature is the OmniGrip’s semi-automatic or fully manual control capabilities. You can assign the robot to a location to pick up an item. Then let it automatically recognize, pick up, and place the object in the pre-determined location. You can even remotely control the arm via the app when necessary. Although internet connection latency still limits this feature and sometimes makes it less smooth than users expect, it holds vast potential. Future updates promise significant improvements.

Exceptional Cleaning Power and Smart Edge Handling

In addition to the “unique” feature of the OmniGrip arm, the Roborock Saros Z70 also possesses a series of advanced technologies. These include various cleaning modes that meet the diverse needs of today’s households. If you’re looking for the robot vacuum with strongest suction, the Roborock Saros Z70 ranks at the top. With a suction force of up to 22,000 Pa, the Saros Z70 is powerful in cleaning stubborn dirt and debris on both hard floors and carpets. This is an impressive number, helping to quickly remove stubborn dirt, ensuring your home is always clean and tidy.

To enhance cleaning efficiency, the Saros Z70 is equipped with FlexiArm technology. It features a retractable side brush and a rotating mop, both of which maximize the ability to clean corners. Although it does not utilize a vibrating mop or a mop roller, the rotating mop integrated into this product remains the best solution for cleaning edges and wall corners. It is powerful enough to remove common stains.

Smooth Navigation Across All Surfaces

Another strong point of the Saros Z70 is the AdaptiLift chassis lifting system, which enables the robot to overcome obstacles up to 4 cm high easily. You may have also encountered difficulties when robot vacuum cleaners cannot go through small doors or gaps between areas. Thanks to AdaptiLift, the Saros Z70 can navigate all terrain smoothly within the house, from the balcony area to the bathroom steps. This not only helps the robot clean more thoroughly. It also expands its cleaning range, allowing it to better respond to apartments with complex designs.

For those seeking a room mapping robot vacuum that can adapt to complex layouts, the Saros Z70 is well-equipped. To perform the cleaning task accurately, Saros Z70 integrates StarSight 2.0 navigation technology. This system harmoniously combines a LiDAR sensor, VertiBeam 3-axis structured light, and an RGB camera with LED. It also includes a vertical laser, enabling the robot to recognize and avoid obstacles on its path. With this modern positioning technology, not only large areas but also hidden, narrow corners under cabinets and tables are thoroughly cleaned. This is especially useful for families with complex home layouts, where every corner requires attention.

Long Battery Life and Smart Base Station Design

Roborock Saros Z70 is equipped with a battery capacity of up to 6,400 mAh, similar to its predecessor Saros 10/10R. This impressed me because the robot body of the Saros Z70 has taken up space for the mechanical arm. However, the company still optimizes the space very well to integrate other equipment, including a full high-capacity battery.

An indispensable part of the robot vacuum experience is the charging station – and the Saros Z70 comes with the Rockdock Ultra 4.0 charging station, featuring a compact design and modern features. The charging station not only automatically charges the robot’s battery but also cleans itself. It washes the mop with hot water up to 80°C, dries it with hot air at 55°C, automatically collects dust, and even cleans the charging station. This saves you time and effort, ensuring that every time the robot starts up, it is “ready to fight” against dirt.

Final Line

In this Roborock Saros Z70 quick review, it’s clear that the Z70 isn’t just another robot vacuum—it’s an intelligent sweeping robot built to deal with the kind of mess real homes have. The addition of the OmniGrip arm alters our perspective on automation in cleaning. It doesn’t just avoid socks and shoes—it picks them up, keeping the job going without interruption. Combined with serious suction, a clever corner-cleaning design, and all-terrain movement, the Z70 effortlessly handles dust, clutter, and floor transitions with ease.

There are a few areas for improvement, such as how it handles oddly shaped objects or the slight lag in remote control, but these are small trade-offs for what this robot offers. If your space is lived-in and full of life, it likely requires more than just surface cleaning. The Saros Z70 is one of the most practical and advanced options available. Overall, the Roborock Saros Z70 stands out as a smart floor cleaner and vacuum robot, combining strength, intelligence, and innovation in one device.
